What is your OS and Xcode version? Also make sure that xcode-select --print-path is pointing to the correct place (actual Xcode, not the command line tools. For me it returns /Applications/Xcode.app/Contents/Developer)

I just did brew rm llvm and tried again. This time I get a different error

I have macOS 10.14.5 on this machine, but I do have an older laptop with 10.13 at home; I will try that out later on.

I already tried on another computer and it succeeded. I need to use the first computer though and I am not sure how to proceed. Any tips would be greatly appreciated.
